BACKGROUND 1. Field of the Invention

The present invention relates generally to an electronic device, and more particularly, to a housing, a method of manufacturing the housing, and an electronic device including the housing.

2. Description of the Related Art

With the development of electronic and telecommunication techniques, electronic devices perform various functions and may have a convergence function which performs one or more functions in combination.

Recently, a technological gap between electronic devices produced by different manufacturers has been remarkably decreased. Thus, there is a tendency to increase the rigidity of the electronic device which gradually becomes slimmer and to emphasize a design aspect in order to satisfy a consumer's need. As part of such a tendency, various constitutional elements (e.g., an exterior) of the electronic device have been implemented with a metal substance to satisfy the appeal for a good material quality and good outer appearance of the electronic device. Further, there is an effort to solve problems caused by the use of the metal substance, such as being vulnerable to rigidity, a ground problem (e.g., an electric shock, etc.), a decrease in antenna radiation performance, or the like.

In particular, when an edge portion of the electronic device is formed with the metal material, the electronic device may include a segmented portion, of which one part is segmented and filled with a non-metal member. However, the housing formed with the metal material is still vulnerable to rigidity. In particular, a metal bezel of the electronic device is frequently damaged or deformed, when the electronic device is dropped.

SUMMARY

The present invention has been made to solve at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below.

Accordingly, an aspect of the present invention is to provide a housing of which rigidity can be reinforced only with a structure of a metal bezel itself, a method of manufacturing the housing, and an electronic device including the housing.

Another aspect of the present invention is to provide a housing implemented to satisfy a consumer's need for a good outer appearance even if a housing formed with a metal material is applied, a method of manufacturing the housing, and an electronic device including the housing.

Another aspect of the present invention is to provide a housing capable of protecting an electronic device from an external impact by smoothly performing a function of the electronic device while reinforcing rigidity, a method of manufacturing the housing, and an electronic device including the housing.

According to an aspect of the present invention, a mobile phone is provided including a metal bezel having a left bezel portion and a right bezel portion and covering at least one part of an outer circumferential edge of a main body of the mobile phone, wherein upper and lower corner bezel portions of the left and right bezel portions are formed to be thicker outwardly in comparison with a middle portion of the left and right bezel portions.

According to another aspect of the present invention, a mobile phone is provided including a chamfer formed on a metal bezel covering at least one part of a rear side and a lateral side of a main body of the mobile phone, wherein the chamfer is formed between a front side or the rear side of the main body and a lateral side of the main body, and at least one non-metal segmented portion formed in one part of the metal bezel, wherein a paint is spread on a lateral wall of the metal bezel such that the lateral wall is covered and the at least one non-metal segmented portion on is exposed.

According to another aspect of the present invention, a housing is provided including a metal bezel serving as at least one area of the housing, and a non-metal member which is insert-injected to the metal bezel and serves as the remaining areas of the housing, wherein the metal bezel includes left, right, upper, and lower bezel portions, and a rear bezel portion formed to be extending from at least one part of the left, right, upper, and lower bezel portions to one part of a rear side of the housing, wherein upper left and right corner bezel portions in which the left and right bezel portions are met in the upper bezel portion and lower left and right corner bezels in which the left and right bezel portions are met in the lower bezel portion are formed to have a thickness thicker than a thickness of the left and right bezel portions.

FIG. 1 illustrates a network environment 100 including an electronic device 101 according to an embodiment of the present invention. The electronic device 101 includes a bus 110, a processor 120, a memory 130, an input/output interface 140, a display 150, and a communication interface 160

The bus 110 is a circuit for connecting the aforementioned constitutional elements to each other and for delivering communication (e.g., a control message) between the aforementioned constitutional elements.

The processor 120 receives an instruction from the aforementioned different constitutional elements (e.g., the memory 130, the input/output interface 140, the display 150, the communication interface 160, etc.), for example, via the bus 110, and thus interprets the received instruction and executes arithmetic or data processing according to the interpreted instruction.

The memory 130 stores an instruction or data received from the processor 120 or different constitutional elements (e.g., the input/output interface 140, the display 150, the communication interface 160, etc.) or generated by the processor 120 or the different constitutional elements. The memory 130 may include programming modules such as a kernel 131, a middleware 132, an Application Programming Interface (API) 133, an application 134, and the like. Each of the aforementioned programming modules may consist of software, firmware, or hardware entities or may consist of at least two or more combinations thereof.

The kernel 131 controls or manages the remaining other programming modules, for example, system resources (e.g., the bus 110, the processor 120, the memory 130, etc.) used to execute an operation or function implemented in the middleware 132, the API 133, or the application 134. In addition, the kernel 131 provides a controllable or manageable interface by accessing individual constitutional elements of the electronic device 101 in the middleware 132, the API 133, or the application 134.

The middleware 132 performs a mediation role so that the API 133 or the application 134 communicates with the kernel 131 to exchange data. In addition, regarding task requests received from the application 134, for example, the middleware 132 performs a control (e.g., scheduling or load balancing) for the task requests by using a method of assigning a priority capable of using a system resource (e.g., the bus 110, the processor 120, the memory 130, etc.) of the electronic device 101 to at least one of the applications 134.

The API 133 may include at least one interface or function (e.g., instruction) for file control, window control, video processing, character control, and the like, as an interface capable of controlling a function provided by the application 134 in the kernel 131 or the middleware 132.

The application 134 may include an Short Message Service (SMS)/Multimedia Messaging Service (MMS) application, an e-mail application, a calendar application, an alarm application, a health care application (e.g., an application for measuring a physical activity level, blood sugar level, etc.) or an environment information application (e.g., atmospheric pressure, humidity, or temperature information). Alternatively, the application 134 may be an application related to an information exchange between the electronic device 101 and an external electronic device (e.g., an electronic device 104 or server 106). The application related to the information exchange may include, for example, a notification relay application for relaying specific information to the external electronic device or a device management application for managing the external electronic device.

For example, the notification relay application may include a function of relaying notification information generated in another application (e.g., an SMS/MMS application, an e-mail application, a health care application, an environment information application, etc.) of the electronic device 101 to the external electronic device. Alternatively, the notification relay application may receive notification information, for example, from the external electronic device and provide it to the user. The device management application may manage, for example, a function for at least one part of the external electronic device which communicates with the electronic device 101.

Examples of the function include turning on/turning off the external electronic device itself (or some components thereof) or adjusting of a display illumination (or a resolution), and managing (e.g., installing, deleting, or updating) an application which operates in the external electronic device or a service (e.g., a call service or a message service) provided by the external electronic device.

The application 134 may include an application specified according to attribute information (e.g., an electronic device type) of the external electronic device. For example, if the external electronic device is an MP3 player, the application 134 may include an application related to a music play. Similarly, if the external electronic device is a mobile medical device, the application 134 may include an application related to a health care. The application 134 may include at least one of a specified application in the electronic device 101 or an application received from the external electronic device.

The input/output interface 140 relays an instruction or data input from a user by using a sensor (e.g., an acceleration sensor, a gyro sensor) or an input device (e.g., a keyboard or a touch screen) to the processor 120, the memory 130, or the communication interface 160, for example, via the bus 110. For example, the input/output interface 140 may provide data regarding a user's touch input via the touch screen to the processor 120. In addition, the input/output interface 140 outputs an instruction or data received from the processor 120, the memory 130, or the communication interface 160 to an output device (e.g., a speaker or a display), for example, via the bus 110. For example, the input/output interface 140 may output audio data provided by using the processor 120 to the user via the speaker.

The display 150 displays a variety of information (e.g., multimedia data or text data) to the user.

The communication interface 160 connects a communication between the electronic device 101 and the external electronic device 104 or the server 106. The communication interface 160 can include an antenna. For example, the communication interface 160 may communicate with the external device by being connected with a network 162 through wireless communication or wired communication. The wireless communication may include, for example, at least one of Wireless Fidelity (Wi-Fi), Bluetooth (BT), Near Field Communication (NFC), Global Positioning System (GPS), and cellular communication (e.g., Long Term Evolution (LTE), LTE Advanced (LTE-A), Code Division Multiple Access (CDMA), Wideband CDMA (WCDMA), Universal Mobile Telecommunications System (UMTS), Wireless Broadband (WiBro), Global System for Mobile Communication (GSM), etc.). The wired communication may include, for example, at least one of Universal Serial Bus (USB), High Definition Multimedia Interface (HDMI), Recommended Standard (RS)-232, and Plain Old Telephone Service (POTS).

The network 162 may be a telecommunications network. The telecommunications network may include at least one of a computer network, an internet, an internet of things, and a telephone network. A protocol (e.g., a transport layer protocol, a data link layer protocol, or a physical layer protocol) for communications between the electronic device 101 and an external device may be supported in at least one of the application 134, the application programming interface 133, the middleware 132, the kernel 131, and the communication interface 160.

Although a metal bezel served as a housing of an electronic device is described herein in various embodiments of the present invention, the present invention is not limited thereto. For example, the present invention is also applicable to a housing having a different construction other than that of the electronic device, and may be applied as an internal constitutional element rather than an exterior.

Although a metal bezel extending up to at least one part of a rear side along an edge is described in various embodiments of the present invention, a metal bezel which is selectively applicable to various areas of an electronic device, for example, which is applied to only one part of an edge of the electronic device or is not applied to the rear side, also complies with technical features of the present invention.

FIG. 2A is a perspective view of an electronic device 200 to which a metal bezel 210 is applied according to an embodiment of the present invention. FIG. 2B is a plan view of part of the electronic device 200 illustrating important parts of the electronic device 200 according to an embodiment of the present invention.

Referring to FIG. 2A and FIG. 2B, a display 201 is installed in a front side 207 of the electronic device 200. A speaker 202 for receiving and outputting a voice of a counterpart user may be installed in an upper side of the display 201. A microphone 203 for transmitting a voice of a user of the electronic device to the counterpart user may be installed in a lower side of the display 201.

According to an embodiment of the present invention, components for performing various functions of the electronic device 200 may be placed near an area in which the speaker 202 is installed. The components may include at least one sensor module 204. The sensor module 204 may include, for example, an illumination sensor (e.g., an optical sensor), a proximity sensor (e.g., an optical sensor), an infrared sensor, and an ultrasonic sensor. According to an embodiment of the present invention, the components may include at least one of a camera 205 and a Light Emitting Diode (LED) indicator 206 to allow the user to recognize state information of the electronic device 200.

According to an embodiment of the present invention, the electronic device 200 may include the metal bezel 210 as a housing. According to an embodiment of the present invention, the metal bezel 210 may be disposed along an edge of the electronic device 200, and may extend to at least one area of a rear side of the electronic device 200 extending from the edge. According to an embodiment of the present invention, the metal bezel 210 defines a thickness of the electronic device along the edge of the electronic device 200, and may be formed in a closed-loop shape. However, the present invention is not limited thereto, and thus the metal bezel 210 may also be formed to serve as at least one part of the thickness of the electronic device 200. According to an embodiment of the present invention, the metal bezel 210 may be disposed only in at least one area of the edge of the electronic device 200. According to an embodiment of the present invention, when the metal bezel 210 serves as one part of the housing of the electronic device 200, the remaining parts of the housing may be formed of a non-metal member. In this case, the metal bezel 210 may be formed in such a manner that the non-metal member is assembled or insert-injected.

According to an embodiment of the present invention, the metal bezel 210 has a closed-loop shape along the edge, and may be disposed to serve as the entire thickness of the electronic device 200. According to an embodiment of the present invention, when the electronic device 200 is viewed from the front, the metal bezel 210 may be formed of a right bezel portion 211, a left bezel portion 212, an upper bezel portion 213, and a lower bezel portion 214. According to an embodiment of the present invention, the metal bezel 210 may include an upper-right corner bezel portion 215 in which the right bezel portion 211 and the upper bezel portion 213 meet and an upper-left corner bezel portion 216 in which the left bezel portion 212 and the upper bezel portion 213 meet. According to an embodiment of the present invention, the metal bezel 210 may include a lower-right corner bezel portion 218 in which the right bezel portion 211 and the lower bezel portion 214 meet and a lower-left corner bezel portion 217 in which the left bezel portion 212 and the lower bezel portion 214 meet. The metal bezel 210 may also include one or more segmented portions 219, which may be non-metal and formed in a specific interval between at least two parts of the metal bezel.

FIG. 3A illustrates a state in which a non-metal member 220 is insert-injected to a metal bezel 210 according to an embodiment of the present invention.

Referring to FIG. 3A, the non-metal member 220 may be inserted-injected to the metal bezel 210, and thus, the non-metal member 220 and the metal bezel 210 may be complete as one housing. According to an embodiment of the present invention, the metal bezel 210 may be disposed at an edge and at least one area of a rear side of the electronic device. According to an embodiment of the present invention, the metal bezel 210 may also extend up to at least one area of an inner surface of the electronic device 200. According to an embodiment of the present invention, the non-metal member 220 may be a member formed from a synthetic resin material. However, the present invention is not limited thereto, and thus various non-conductive dielectric materials may be applied.

According to an embodiment, to reinforce rigidity of the metal bezel 210, the upper-left corner bezel portion 215 and the upper-right corner bezel portion 216 may be formed to have a thickness (i.e., the thickness of the metal bezel 210) thicker than that of right bezel portion 211 and left bezel portion 212.

FIG. 3B illustrates important parts in a state in which a non-metal member 220 is insert-injected to a metal bezel 210 according to an embodiment of the present invention.

Referring to FIG. 3B, the metal bezel 210 includes a segmented portion 219 in which at least one area of an upper bezel portion 213 is segmented. According to an embodiment of the present invention, the segmented portion 219 may be formed together when the non-metal member 220 is insert-injected to the metal bezel 210. When the electronic device 200 is used as a communication device, by the use of the segmented portion 219, the upper bezel portion 213 may be used as an antenna radiator together with an antenna radiator disposed inside of the electronic device.

Conventionally, the segmented portion is included in one area (i.e., a portion E of FIG. 3B) of each of right and left bezel portions 211 and 212 of FIG. 3B. However, in this manner, corner bezel portions 215 and 216 are also used as an antenna radiator, and cannot be formed with an increased thickness in order to ensure antenna performance.

However, according to an embodiment of the present invention, instead of using the segmented portion indicated by the portion E of FIG. 3B, at least one segmented portion 219 is disposed in a specific area of the upper bezel portion 213, and the corner bezel portions 215 and 216 are formed to have a thickness thicker than that of the right and left bezel portions 211 and 212 to reinforce rigidity, thereby being able to prevent deformation and damage caused by external impacts.

FIG. 4A is an enlarged view illustrating important parts of a portion A of FIG. 3B according to an embodiment of the present invention; and FIG. 4B is a cross-sectional view illustrating important parts of the portion A of FIG. 3B according to an embodiment of the present invention.

Referring to FIG. 4A and FIG. 4B, in order to secure rigidity of an electronic device, in particular, rigidity of a vulnerable corner bezel portion, a corner bezel portion of a metal bezel 210 is formed to be relatively thick, and also a non-metal member 220 is insert-injected thereto. Therefore, a joining force with respect to the non-metal member 220 can be reinforced.

According to an embodiment of the present invention, in each corner bezel portion of the metal bezel 210, a reinforcing protrusion 2101 is formed to be inserted by a specific length in an inward direction with respect to the metal bezel. Thereafter, the non-metal member 220 may be insert-injected to cover the reinforcing protrusion 2101. Therefore, a first supporting portion 2201 of the non-metal member 220 may be insert-injected to a first part of the reinforcing protrusion 2101, and a second supporting portion 2202 of the non-metal member 220 may be insert-injected to a second part of the reinforcing protrusion 2101. In this case, a contact area between the metal bezel 210 and the non-metal member 220 is extended, and thus rigidity of each corner bezel portion of the metal bezel 210 can be secured.

FIG. 5A to FIG. 5C are cross-sectional views illustrating important parts viewed respectively from the reference lines B, C, and D of FIG. 3B according to an embodiment of the present invention.

According to an embodiment of the present invention, a thickness is constant from each corner bezel portion to upper and lower bezel portions in terms of an outer appearance. However, if the upper and lower bezel portions are used as an antenna radiator, antenna radiation performance may deteriorate due to an increase in the thickness.

As shown in FIG. 5A, the cornel bezel portion 216 may be formed such that a cross-section thereof is also thick, whereas as shown in FIG. 5B and FIG. 5C, the upper bezel portion 213 may be formed to have slits 2102 and 2103 inwardly in a lengthwise direction of the upper bezel portion 213. The slits 2102 and 2103 prevent performance deterioration of an antenna radiator which is covered by the metal bezel 210, and if the upper bezel portion 213 is used as an antenna radiator, improved antenna radiation performance can be achieved. According to an embodiment of the present invention, the non-metal member 220 fills the aforementioned slits 2102 and 2103 of the upper bezel portion 213 after insert-injection, and since the non-metal member 220 is a dielectric material, it does not have an effect on antenna radiation performance even if a thickness thereof is increased.

FIG. 6A illustrates a state in which a non-metal member 620 is insert-injected to a metal bezel 610 according to another embodiment of the present invention.

Referring to FIG. 6A, the metal bezel 610 may include an edge serving as a lateral side of an electronic device which defines the thickness of the electronic device and one area of a rear side of the electronic device, and the non-metal member 620 may be insert-injected in the remaining areas. However, the present invention is not limited thereto, and only one area of the edge of the electronic device may be formed as the metal bezel 610. According to an embodiment of the electronic device, the edge may include left, right, upper, and lower bezel portions 611, 612, 613, and 614. After the non-metal member 620 is insert-injected, painting may be performed on the entirety of the metal bezel 610 by including a boundary surface thereof. A boundary portion between the metal bezel 610 and the non-metal member 620 is not recognizable by a naked eye due to the painting process, thereby providing a good outer appearance.

FIG. 6B is a perspective view illustrating important parts of a state in which an outer surface is painted after a non-metal member 620 is inserted-injected to a metal bezel 610 according to another embodiment of the present invention.

Referring to FIG. 6B, a part of the rear portion 615, on which painting has been performed after the non-metal member 620 is insert-injected to the metal bezel 610, (in the dotted circle) is shown in an enlarged view. A chamfer 616 may be finally formed along a lengthwise direction in a boundary portion between the rear portion 615 of the metal bezel 610 and each of lateral bezel portions 611, 612, 613, and 614. The chamfer 616 may be formed by a diamond cutting process.

According to the present invention, after the painting, as a final process, the chamfer 616 may be formed in a lengthwise direction in a boundary portion between the upper bezel portion 613 and the rear bezel portion 615 of the metal bezel 610. The non-metal member 620 may be exposed in the chamfer 616 because of a chamfering process after the painting process. That is, a segmented portion formed in a boundary portion in the metal bezel 610 by insert-molding of the non-metal member 620 is not exposed to the outside except for the chamfer 616 having a relatively small area (i.e., the non-metal member 620) due to the painting, and thus the electronic device may have a good outer appearance.

FIG. 6C is a cross-sectional view illustrating important parts of a state in which a surface treatment layer for preventing corrosion is formed in a chamfer area according to another embodiment of the present invention.

Referring to FIG. 6C, a metal portion may be exposed to the outside due to a chamfer 616 formed in a corner of a metal bezel 610, and the exposed metal portion may be vulnerable to corrosion. Therefore, a surface treatment layer 619 for preventing the corrosion may be further formed on the surface of a painting area including the chamfer 616. According to another embodiment of the present invention, the surface treatment layer 619 may be formed only in the area of chamfer 616.

According to another embodiment of the present invention, the surface treatment layer 619 may include a primer layer 619-1 laminated with a specific thickness on the surface of the painting area and an Anti Fingerprint (AF) coating layer 619-2 laminated on the surface of the primer layer 619-1.

According to the present invention, the primer layer 619-1 is provided to smoothly laminate the AF coating layer 619-2, and may be formed by performing a vacuum deposition or sputtering process on a SiO₂ type or AI₂O₃ type material. According to another embodiment of the present invention, the primer layer 619-1 may be formed not only with a single material but also by depositing a material in which SiO₂ and AI₂O₃ are mixed in a specific ratio.

According to the present invention, the primer layer 619-1 may be formed as a multi-layered layer in such a manner that the AI₂O₃ material is formed with a specific thickness and the SiO₂ material is additionally formed with a specific thickness. The primer layer 619-1 may be formed with a thickness of 20 to 2000 nanometers.

The AF coating layer 619-2 may be formed by depositing a material having excellent anti-friction, anti-fouling, and chemical resistance properties. According to another embodiment of the present invention, a ceramic coating layer may be applied instead of an AF coating layer.

FIG. 7A and FIG. 7B are cross-sectional views viewed from the reference line F of FIG. 6A according to an embodiment of the present invention.

Referring to FIG. 7A, a metal bezel 610 may be formed as a housing. The metal bezel 610 may support an internal bracket 630. A window 640 may be installed in an upper side of the internal bracket 630. Although not shown, a display may be disposed between the window 640 and the bracket 630.

According to the present invention, the metal bezel 610 may have a chamfer forming area 616 formed in a boundary portion between a rear portion 615 and a right bezel portion 611. According to another embodiment of the present invention, the chamfer forming area 616 may be flat. Also, between the right bezel portion 611 and the window 640, a chamfer forming area 618 may also be formed in a boundary portion with respect to an upper front area 617 of the electronic device. Although not shown, the chamfer forming area 618 may be formed in each of a lower end portion and upper end portion of the right bezel portion 611, that is, in a boundary portion between a front side and rear side of the electronic device.

Referring to FIG. 7B, the chamfer forming areas 616 and 618 may be formed in an outwardly curved shape. Although not shown, according to another embodiment of the present invention, the chamfer forming areas 616 and 618 may be formed in an inwardly curved shape. According to another embodiment of the present invention, at least two chamfers may be formed consecutively to be neighboring to each other in a boundary portion between the right bezel portion 611 and the rear bezel portion 615 of the electronic device or in a boundary portion between the right bezel portion 611 and the upper front area 617.

FIG. 8 is a flowchart for manufacturing a metal bezel (e.g., a housing) of an electronic device according to an embodiment of the present invention. FIG. 9A to FIG. 9C illustrate an operation based on the manufacturing process of the metal bezel of FIG. 8 according to the present invention.

The process of FIG. 8 will be described with reference to the drawings of FIG. 9A to FIG. 9C. FIG. 9A illustrates a front view and a rear view of the metal bezel 610 having a non-metal member insert-injected. FIG. 9B illustrates a flattening process. FIG. 9C illustrates a view of the electronic device after a printing process.

Referring to FIG. 8, in step 801, a metal bezel 610 without a non-metal member is manufactured. As shown in FIG. 9A, the metal bezel 610 may be formed with various metal materials such as aluminum, magnesium, Steel Use Stainless (SUS), etc., and casting, pressing, or the like may be used to complete a desired molding product. As shown in FIG. 9A, the metal area of the metal bezel 610 may include a right bezel portion 611, left bezel portion 612, upper bezel portion 613, and lower bezel portion 614 serving as an edge of the electronic device and defining its thickness, and may include a rear bezel portion 615 connected to at least one area of each of the bezel portions 611, 612, 613, and 614. The rear bezel portion 615 may be disposed in at least one area of a rear side of the electronic device.

In step 803, a non-metal material is insert-injected to the formed metal bezel to fill a portion in which a metal area is not provided, and as shown in FIG. 9A.

In step 805, a flattening process is performed on a boundary portion of the metal bezel 610 and the non-metal bezel 620. Referring to FIG. 9B, in the flattening process, buffing may be performed not only on a boundary portion of the metal bezel 610 and the non-metal bezel 620, but also on all of a rear bezel portion 615 and each of bezel portions 611, 612, 613, and 614. According to another embodiment of the present invention, the buffing may be performed more than twice.

In step 807, painting is performed on the entire outer surface of the metal bezel 610, of which flattening is complete. According to such a painting process, as shown in FIG. 9C, a boundary area may be hidden by applying heterogeneous materials with respect to the metal bezel 610. According to the present invention, by the use of the painting process, the housing of the electronic device may appear to be formed with a single material and thus provides a good outer appearance. According to the present invention, the painting process may include a soft-feel process to provide a user with an excellent tactility and texture depending on a type of paint to be applied (e.g., a natural substance paint).

In step 809, a chamfer 616 may be formed in a lengthwise direction in a boundary portion between each of the bezel portions 611, 612, 613, and 614 and the rear bezel portion 615. According to the present invention, the chamfer 616 may provide a good outer appearance of the electronic device by partially exposing the metal material of the metal bezel 610, and may provide an excellent grip feel to a user in comparison with an angular corner.

FIG. 10A to FIG. 10E illustrate a flattening process and a painting process after a non-metal member 620 is insert-injected to a metal bezel 610 with respect to the reference line G of FIG. 9A according to an embodiment of the present invention.

As shown in FIG. 10A, if the non-metal member 620 is insert-injected to the metal bezel 610, a step difference portion 6201 or a gap 6202 may be produced in a boundary portion between heterogeneous materials. An outer surface may partially protrude due to the step difference portion 6201 even if the painting process is performed, and one portion of the outer surface is dented due to the gap 6202.

The step difference portion 6201 may be removed through buffing as shown in FIG. 10B, and a primer 650 with a specific thickness may be laminated as shown in FIG. 10C. According to an embodiment of the present invention, the primer 650 may use putty, and may fill the gap 6202 of the boundary portion between the aforementioned heterogeneous materials.

Thereafter, as shown in FIG. 10D, after the primer 650 is hardened, buffing is performed again so that an area of a metal bezel and an area of a non-metal member form a flat-plane. Thereafter, as shown in FIG. 10E, a painting layer 660 may be formed by spreading a paint on the surface of the primer 650 after buffing Thereafter, chamfering may be performed.

FIG. 11A and FIG. 11B illustrate a chamfer 616 located near an ear-jack hole 671 of an electronic device and a processing path of chamfering according to another embodiment of the present invention.

Referring to FIG. 11A, the electronic device includes an ear-jack assembly for accommodating an ear plug of a headset. In this case, the ear-jack hole 671 for accommodating the ear plug may be generally disposed on a lateral bezel portion of the electronic device. In addition, the ear-jack hole 671 may accommodate the ear-jack assembly, and a mold portion 670 may be formed together so that the ear-jack hole 671 can be electrically isolated from a metal bezel formed with a metal material. According to the present invention, the ear-jack hole 671 and the mold portion 670 may be included in a processing path of the aforementioned chamfer 616. Since the mold portion 670 is processed together by the forming of the chamfer 616, a thickness of an ear-jack hole portion becomes thicker under the conventional chamfer shown in FIG. 11B, which may result in being partially vulnerable to rigidity.

According to the present invention, when moving a processing tool (e.g., a diamond cutting tool) for processing the chamfer 616, as shown in FIG. 11A, a thickness of the chamfer 616 towards an ear-jack hole portion may be reinforced by the use of an improved chamfer of FIG. 11B by changing the processing direction between a horizontal direction and a vertical direction using the processing tool. According to the present invention, when processing the chamfer of the ear-jack hole portion, a processing path of the processing tool may be moved in a direction away from the ear-jack hole.

According to an embodiment of the present invention, such a chamfering method may be used not only for a case of using the ear-jack hole but also for a case where the processing tool passes various electronic component accommodating spaces (e.g., an interface connector port, a microphone hole, a speaker hole, etc.) which require an opening exposable to an outer surface of the electronic device.

FIG. 12A illustrates a structure in which a secondary housing 1230 formed with a non-metal material is assembled in a metal bezel 1210 according to another embodiment of the present invention.

Referring to FIG. 12A, a secondary housing 1230 formed with a non-metal member may be insert-injected to the metal bezel 1210, and thus the metal bezel 1210 with the secondary housing 1230 may be complete as a housing of the electronic device. According to the present invention, the metal bezel 1210 may be disposed in an edge and at least one area of a rear side of the electronic device. The metal bezel 1210 may also extend to at least one area of an inner surface of the electronic device. An edge of the metal bezel 1210 may include right, left, upper, and lower bezel portions 1211, 1212, 1213, and 1214.

According to the present invention, the secondary housing 1230 may be formed with a non-metal material, or the secondary housing 1230 may be formed in such a manner that a metal material is assembled in the non-metal material. Also, the secondary housing 1230 may be formed in such a manner that the non-metal material is insert-injected to the metal material.

According to the present invention, the secondary housing 1230 may be formed in such a manner that it is not physically in contact with the metal bezel 1210 even if the metal material is included. This is for preventing an electric shock accident which may occur when current is applied to the metal bezel 1210 when electronic components (e.g., a Printed Circuit Board (PCB)) included in the secondary housing 1230 are used.

FIG. 12B illustrates a structure of a secondary housing (e.g., a bracket) 1230 and PCB 1240 applied to the metal bezel 1210 of FIG. 12A according to an embodiment of the present invention.

Referring to FIG. 12B, the secondary housing (e.g., the bracket) 1230 including the PCB 1240 may be further disposed inside a metal bezel 1210. According to another embodiment of the present invention, the entirety of the secondary housing 1230 may be formed of a nonconductive member (e.g., synthetic resins), or may be assembled or insert-injected together with a metal member (e.g., a reinforcement plate 1231 for supporting a battery pack, an interface connector port 1241, etc.). In this case, the metal member 1231 may be disposed not to be in contact with the metal bezel 1210, or may be disposed to be electrically isolated from the metal bezel 1210 extending to a lateral side of the electronic device. The PCB 1240 may also be disposed to be electrically isolated from the metal bezel 1210, thereby being able to prevent the electric shock accident.

FIG. 13 is a cross-sectional view illustrating a state in which an interface connector port 1241 is applied to a metal bezel 1210 according to an embodiment of the present invention.

Referring to FIG. 13, a non-metal member 1220 may be injected through an opening 1221 for accommodating the interface connector port 1241 in order to electrically isolate the interface connection port 1241 and metal bezel 1210 formed with a metal material. Therefore, by the use of the non-metal member 1220 disposed around the interface connector port 1241, current which flows through the interface connector port 1241 may be prevented from causing an electric shock accident which may occur when current is applied to the metal bezel 1210.

According to various embodiments of the present invention, it is possible to provide a housing which can be configured to smoothly perform a function of an electronic device while reinforcing rigidity by using a structure of the housing itself and to have a good outer appearance, and an electronic device including the housing.
